China will not be content to only play defense in an escalating trade war with the United States, a widely read Chinese tabloid warned, as President Donald Trump was expected to announce new tariffs on $200 billion in Chinese goods as early as Monday.

Beijing may also decline to participate in proposed trade talks with Washington later this month if the Trump administration goes ahead with the additional tariffs, the Wall Street Journal reported on Sunday, citing Chinese officials.

The Journal report quoted one senior Chinese advisory official saying China would not negotiate “with a gun pointed to its head.”The United States and China have already levied duties on $50 billion worth of each other’s goods in an intensifying row that has jolted global financial markets in the past few months.
